H.W.#(2).. Surface treatments can be divided in three sectors that are : 1- Surface Engineering to change the surface metallurgy. Like Flame hardening and laser melting. 2- Surface Engineering to change the surface chemistry. Like laser alloying 3- Surface Engineering to add a surface layer or coating. Like hot dipping galvanising Put each of the followings in the right sector: Shoot peening Aluminium Anidizing Cladding Electroplating Thermal spraying

Metal Casting

Metal casting is described as a manufacturing process in which a mold cavity is produced by sand, and molten metal is filled inside a mold cavity. The desirable shaped object is achieved after the solidification of molten metal. Large metal objects like machine beds, motor bodies, and others can easily be manufactured using metal casting. The place or shop where metal casting is performed is called foundry.
